Mad project from 2006 aimed at creating a public domain Lisp OS. I spent most of the time playing around with the Emacs-like editor. Derived from CMUCL 18c.

For info on building the system see the System Building docs in the source (especially Build Tools, Compiling the C, etc).

Note that Nightshade will segfault on recent systems due to stack protection being turned on. I last had it working on Ubuntu 20.04.
